ROTARY PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 476,906, dated June 14, 1892.

Application filed March 21, 18 9 1.

.To 0. whom it may concern:

Be it known that I, HORACE BALDWIN THOMPSON, a citizen of the United States, re siding at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Rotary Printing-Machine, of which the following is a specification.

My invention relates to an improvement in rotaryprinting-machines and itconsistsin the combination of parts hereinafter described, and particularly pointed out in the claims, and is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my machine. Fig. 2 is an end View showing the ends of the rules used to separate the lines of type, the type, and a part of a slotted disk used to hold the ends of the rules. Fig. 3 is a longitudinal View of a section of the type-roller, showing the type in position and the blocks which fill up the spaces between the side disks andthe type. It also shows the manner of holding the type on the type-roller. Fig. 4 is a front and end View of the beveled rules. Fig. 5 is a section of the type-roller, showing the type, the ends of the rules, the slotted disk, the flange of a collar, and the blocks used for electrotypes. Figs. 6, 7, and 8 are views showing the inking-rollers and manner of raising one set of rollers from the type and bringing another set of inking-rollers in contact with the electrotypes when difierent colors are used. These latter figures are referred to in detail hereinafter.

Similar-letters refer to similar parts throughout the several views.

The type-roller A is made of a cylinder m (wood or metal) about two inches in diameter and nine inches in length, Figs. 2 and 3. 011 each end of this cylinder or type-bed m is a slotted disk G of metal. These disks are as much greater in radius than the radius of the cylinder at as the length of the body of the type, so that when the bottom of the type rests on the cylinder m the shoulder of the type is even with the periphery of the disks G. Through the center of the cylinder m is a spindle i. The slots 5 in the disks, G are the shape of the rules (Z, as shown in Figs. 4 and 5. The slots .9 are beveled or wedge-shaped, so that the lines of type all stand in line with the radii of the cylinder. These disks G are sc- Serial No. 885,947- (No model.)

cured to the ends of the cylinder m, so that the corresponding slots 3 of the disks are in a line parallel to the roller. Fitting over the disks G are collars D, having'flanges h, Fig. 3. In these collars Dare openingsr r, about half an inch long and the depth of the flange h. These collars D fit on the spindle t' and can be set at any place by means of the set-screws 5c 00. The object of the openings r r is so the rules (Z and the line of type t can be put on or taken off the cylinder m. The flanges hare for the purpose of holding the rules d and the typet in place.

E E, Figs. 5 and (J, are wooden blocks held by screws on the cylinder m. One is intended to hold an electrotype for printing letter-heads and the other for an electrotype of a signature. This last block E follows the last line of type.

a a are inking-rollers, which feed ink to the type t.

n n, Fig. 6, are also inking-rollers, which feed ink to the electrotypes. The roller n is made with flanges Z Z, Fig. 7, on the ends. These flanges Z Z are the thickness of an electrotype and in diameter greater than the ink ing-roller n;

The inking-rollers a and n are mounted on hinged or pivoted arms, pressed forward by means of springs .9

B is a cylinder or roller covered with a yielding substance, (rubber or other material,) and is the impression-cylinder in connection with which the type-cylinder A revolves and coacts.

C is aweb of paper used forprinting. This passes between the rollersA and B up through the leading rollers e e to the cutting device f. The rollers e e are worked by a belt p over pulley-wheels on the shafts of the rollers B and e. The cutting device f is operated by a trip-lever p on the frame and a cam j on the shaft of the type-roller A. All the rollers are journaled in a frame and are worked by friction.

On the periphery of the collars D, Figs. 0 and S, are cams w, in length the width of the electrotype-block E and of such a height that when the electrotype on the block E passes the inkingn-oller a the roller awill be thrown back, as shown in Fig.8, and the electrotype pass under without being inked. As soon as the end 2 of the cam w passes below the roller a the roller a again falls on the type. When the electrotype-block E reaches the inkingroller 01., the flanges Z Z fall into the grooves 'y y, made to receive them, and the electrotype is-inked. The grooves y y are cut on each side of the electrotype and into the block E of sufficient depth to allow the flanges Z Z to drop in and bring theinking-roller n on the electrotype. As soon as the block E passes the roller n the roller it again rides out of the grooves y y and on the upper edges of the rules (Z. The type following the electrotype-block E is not in contact with the roller it. When the signature-electrotype is used on block E ,I use an adjustable flange or cam on both collars D. In the above description I assume the fact that I am printing in two colors-for example, purple and printing the electrotype and signature in black. The pressure of the inking-rollers a and n is by springs 8 The typet used in this machine is made with a slotthrough the body, through which a bar 7a is passed. The ends of the bar 7c fit in blocks 00' the thickness of the type. The blocks 0 0 fill up the spaces between the type and the disks G.

The operation of my machine is as follows:

A line of type 15 being set up in the stick,

(frame used by type-setters,) a bar It is run through the slots to in the type. On the ends of the bar 70 are placedv blocks 0 0' of suffieient length to fill the spaces on both sides of the line of type tand the disks G. The

collars D are turned on the spindle t until the openings r r' are in a line with correspondingv slots 8 s in thedisks G. A'beveled rule d is then placed in theslots ss an da-line of type against the rule (Z. The collars D are then turned until the openings 0'0" are in a line with the next corresponding slots 5 sin the disks G. Another rule (Z and a line of type is placed in the roller A, and so on until the whole composition is placed on the type-roller A. If desired, a block E, containing an electrotype of a signature and one containing alettor-heading, may be placed on the roller in a line with the type. The flanges h on the collars D, projecting over the ends of the blocks 0 0, hold the line of type in position. The rules d separate the lines of type and serve to keep them parallel. The rollers a a have a colored ink and the rollers n it black ink. By means of .the thumb-screws s a pressure is regulated between the type-roller A and the roller B. By turning the crank q the rollers A and B are caused to revolve, and as the electrotype on the block E approaches the inking-roller a the flanges or cams 10 force the roller 0, back, and the electrotype passes. without being inked. As soon as the end 2 of the cam w passes the roller (1 the roller it falls down again and the type receives the ink. When the electrotype reaches the roller n, which is held from the roller A by virtue of the disksZ Z, the disks ZZ' fall into the grooves y y and the inking part of 'the roller n rides on the electrotype. As soon as the disks Z Z reach the opposite side of the ,grooves y yf the roller nis again raised and Zrides on the disks Z Z, which bear on the upper edges of the rules d. As the electrotypes -and type after being inked pass between the rollers A andB, an impression is made on the paper 0. The paper 0 is then carried by means of the rollers e e to the euttingdevice ff, which is worked by the: lever. p and the camj, attached to the spindle 2'. The rollers c e are operated by a belt 19' over. pulleywheels on the rollers B and e.

What I claim, and desire to secure by Letters Patent,is--

1. The combination; with a eylindriealtypebed, of slotted types, bars for holding 'thelatter, rules, blocks, and retaining means arranged at the ends of the bed for holding the type in place, substantially as described;

2. The combination, with a cylindrical'typebed, of slotted types, bars for holding the lat- 'ter, beveled rules, two slotted disks, and re 'taining means arranged at the ends of the bed for holding the type and rules-in place, substantially as described.

3. The combination, witha cylindrical typebed, of slotted types, barsfor holdingthelatter, beveled rules, blocks, two slotted disks, and two flanged collars for holding-thetype and rules in place, substantially as described.

4. The combination, with a cylindrical typebed for holding type or electroplates, of rules, blocks, two radially-slotted disks, and two collars provided with inwardly projecting flanges, substantially as described.

5. The combination, with a cylindriealtypebed, of rules and blocks, a pair of. radiallyslotted disks, and a pair of movable flanged collars, substantially as described.
